best wire guage for 1.5 ohm pt2

[BuzzKillBob]

cant find a good chart that i can understand on what wire to use to get about a 1.5 ohm. im rebuilding the coils for my pt2...i have standard multi meter so no need for a base meter... any help would be appreciated.
also,i tried searching forum through search feature but that thing is kinda useless as it pulls up WAY too much.

You can get 1.5 ohms with just about any gauge. The ohms aren't gauge dependent, they are length dependent. If you are making a micro coil then 28 ga is preferred. For a standard coil 30 - 32 ga is pretty common.

I would go with 30 gauge. You can get a decent amount of wraps that way.

Lol. Dumb question... What would happen if.... I used a spring from an ink pen? I have ohm meter to test first, but I'm just curious is all...

I get 1.6 ohms very consistently when I wrap 30 gauge around a single strand of 2mm ekowool, 7 wraps. Maybe with 7 warps on a single strand of 2mm regular silica you can get 1.4-1.5 ohms. But yeah, 30 gauge I agree.

So does the material used govern the end ohm?

No, just the width, since the wider the wick the more wire you end up using per wrap. Ekowool is hollow so I would just stick a straightened out paperclip and thread it thru for stability while I wrapped the coil. Also probably why I get consistent ohms. What wick do you use?

None yet. Just getting info before attempting

Cool. PM me if you want to try 2mm ekowool. I have a crap ton and I don't use it as much anymore.

The material of the coil makes a massive difference. The material of the wick makes none.

The spring in your ink pen will be steel. You will end up with a dead short across your battery. You do not want to do that.

Nichrome and Kanthal wire are specifically formulated to have high resistances, several orders of magnitude greater than almost every other sort of metal. So you can only use those materials for a coil.

Resistance increases with length and decreases with cross-sectional area. So a long piece of thick wire can have the same resistance as a short piece of thin wire.
